I mixed fed DD1 due to massive weight loss at the beginning but I was very strict about when she had a bottle and basically she used to breastfeed all day and have a big bottle of formula before bed.
She would just feed all the time and never seemed satisfied and this carried on til we stoppped b/fing at 6 months.
With DD2, I started to have the same issues. Having held out and held out with DD1 for things to get better/easier and that never happening I resigned myself pretty early on to the fact that I simply wouldn't be able to spend every waking moment glued to a chair feeeding for 6 months with a toddler to look after as well.
So started topping DD2 up with formula after most feeds from about 4 weeks. Was expecting my milk to be gone but she's 11 weeks old now and will still feed for a while in the morning and a few times a day for 5/10 mins or so.
I doubt she's getting much although we do get a mixture of formula and b/f looking nappies.
I guess my long winded question is - when will I know when my milk has run out completely? Will DD2 just get friustrated at not getting any milk? I intend to carry on going for as long as I can but tbh I expected b/fing to be over now and I guess now I'm getting my hopes up we may be able to keep going a bit longer.
